UNITED STATES ANGEL VARGAS,. or ILoILo, PHILIPPINE ISLANDS.

PLOW.

Application filed.- Ieebruary 3, Serial N0... 616,624.

To all whom it may concern Be it known that I, ANGEL VARGAS, a citizen of the Philippine Islands, residing at Iloile, Philippine Islands, have invented 5 certain new and useful Improvements in.

Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- 1 tains to make and use the same.

My present invention relates to improvements in plows, and itis intended to provide a cheap, simple, light and efficient plow which may be controlled by a single handle 1 and isof the general type used in certain tropical countries, such as. the Philippine Islands.

Such plows are frequently drawn by cara baoor water buffalo, and it is desirable tohave the clevis at a low height above the ground.

The invention is especially intended to provide a light plow which is capable of either light or heavy work as desired, and which may be conveniently shipped in transitand conveniently used according to tropical standards as described.

My invention isespecially intended to provide simplifications of and improvements on the structure shown in my earlier Patent No. 1,020,232, granted March 12, 1912 andv entitled Improvements in plows.

My invention will 'be more fully understood after reference to the accompanying drawings, inwhich like parts are indicated by similar reference symbols throughout the several views, and in which Figure 1 shows a side elevation of the complete plow, the handle beiiig broken 40 away.

Figure 2 is a plan view of the device shown in Fig. 1.

Figure 3 is a View similar to Fig. 2, but

The rearend'of the plow beam is curved downwards as, shown at a. Near the upper arched portion of the plow beam the standard E is attached as. by means of the bolt F. This standard is concave looking from the the; forward end of the plow. The upper end of the standard is provided with a bracket. E through which the bolt F also passes, which. bracket is secured to the standard as by means of the rivets e. The lower end of the standard is bifurcated, as at e and e and is secured to. the landside H by means of the bolts G and nuts 9, the nuts being mounted beneath the plow share so as not to catch in the dirt. The outer ends of the bolts G are countersunk in the landside as shown in Fig. 3.

At its front end the landside is provided with a flanged portion h ,to which the plow share I is attached. This plowshare is connected to the moldboard'; I by means ofthe metal straps K-and K, which are riveted as at k to the plow share I and are bolted, as at k, to the moldboard I, as shown most clearly in Figs. 1 and 3. The bolts la carry nuts which are mounted behind the moldboard so as not to engage the dirt. ,The exposed heads of the rivets 7c and bolts k are countersunk, respectively, in the plow share I and moldboard I, so as to provide a smooth surface.

The moldboard is connected to the standard E by means of the angle brace L. At its rear the landside is provided with an adjustable wear shoe M, which is shown most clearly in Figs. 1 and 3, and this shoe. is provided with a groove m adapted to engage the lower edge of the landside; and the front edge of this shoe is beveled, as at m, and the bottom edge is straight, as at m so as to provide a wear surface for the rear end of the landside. The landside is provided with a notch or lug 71. See Figs. 1 and 3, to engage the bevel edge m of the shoe M; said shoe when in the forward position as shown in Figs. 1 and 3 being held in place by the bolt M" and nut m The handle bar N is provided at its upper end with a handle 12, I referably curved forwards, as shown in higs. l and 3, and its lower end is bent substantially at right angles as at n, and its lower end is secured to the landside by means of the bolts 0 and O and the nuts 0 and 0', as shown most clearly in F ig. 1.

The back of the handle bar rests against the bevel edge m of the shoe M, as shown in Fig. 1. At a suitable height above the shoe M the handle bar is provided with a strap 1, see Figs. 3 and 5, which is riveted as at 20 to the handle bar, and is secured to said handle bar by means of the bolt P and nut 39 The position of the rear end of the plow beam is adjusted inside the strap P by means of suitable wedges Q and Q which are preferably of wood, and driven into place so as to hold the clevis at the desired height above the ground.

It will be obvious that by driving in one direction on one wedge and driving in another direction on the other wedge, the height of the rear end of the plow beam'may be increased or decreased, as desired, and consequently the height of the clevis above the ground may be increased or decreased, as desired.

The rear end of the moldboard is connected to the plow handle by means of the brace R, which brace is connected to the handle bar by means of the bolt P already described. The brace R is connected at its for ward end to the moldboard as by means of the bolts S and nut s, the nut being on the underside of the moldboard, and the head of the bolt being countersunk in the moldboard as shown in Figs. 1 and 2.

It will thus be seen that I provide a cheap, simple and efficient plow which may be easily assembled or taken apart, and from which the parts, such as the plow share, may

be conveniently removed for sharpening, or other repairs, when desired, or from which worn parts may be conveniently removed and fresh parts readily supplied when needed.

It will be noted that the plow is eX- tremely compact in construction, takes up very little room in storage or in shipment,

and is of rugged construction especially adapted for the uses hereinbetore stated.

It will be obvious that various changes might beinade in the construction, combination and arrangement of parts which could be used'without departing from the spirit of my invention; and i do not mean to limit the invention to such details except as particularly pointed out in the claim.

Having thus describedmy invention what I claim and desire to secure by Letters Patent of the United States is I A plow of the character described, comprising a metal beam curved downwards front and rear, a curved standard connected to said beam and bifurcated at its lower end, alandside connected to the bifurcated endsol said standard, the said la-ndside being provided, with a laterally projecting flange at the forward edge, a plow share connected to said flange, a moldboard,con-' nected to said plow share and to said standard, a single handle bar havingits heel bent forwardly at an angle, said bent portion being connected to said landside, a metal strap connected to said handle bar and spaced away therefrom and adapted to receive the rear end of said beam, wedges driven into a space between said strap and said. beam for holding said beam firmly in place, a shoe detachably connected to the rear end of said landside and having an i11- clined edge abutting against said handle bar, and a brace connecting the rear portion of the moldboard with said handle bar.
